The health audit is considered a tool to assist in the management of health services.Through its application, it is possible to obtain a situational diagnosis to intervene in order to obtain changes and improvements; however, there are controversies regarding its accounting-financial and/or assistance quality approach, varying this focus in different contexts and situations, both in the Unified Health System and in supplementary health. The objective of this study is to analyze the scientific knowledge produced about auditing and its contribution to management in hospital care. It is an integrative review, guided by the question "What are the scientific evidences about auditing as a contribution to management in hospital care?", which went through five stages for its elaboration. The primary studies were selected in the LILACS, MEDLINE databases via PubMed, Scopus, Embase and Web of Science.The sample of the integrative review was composed of 18 studies, which were inserted and stored in the EndNote Basic software. To systematize the selected articles, the Rayyan software was used, and for the analysis of similarity of words, Iramuteq was used. The selection of the articles was done in a double conference by two researchers, independently. After the synthesis, the studies were grouped into two categories. "The audit on the qualification of assistance and management processes" groups 16 articles, which bring different strategies, such as the educational process and the implementation of assistance protocols/guidelines, which enable the planning and decision making by the manager to qualify the assistance. The category "Audit and cost management" groups five articles, which bring an important contribution in relation to the adequacy of expenses and costs to redistribute and optimize the resources involved in patient care. The scientific evidence includes knowledge about auditing, which favors hospital management, mainly in interventions for the review and improvement of assistance processes, the implementation of clinical protocols, and the promotion of actions that involve the educational process and the reflection of practice by professionals, providing quality assistance and also enabling cost management.
